J'ai du mal � suivre. Dans la vraie vie, il me semble que ce sera "beaucoup plus". La norme (C99) dit SIZE_MAX ne peut �tre inf�rieur � +65535, PTRDIFF_MIN sup�reur � ?65535 et PTRDIFF_MAX inf�rieur +65535. Les deux derni�res valeurs peuvent sembler �tranges, mais elles sont li�es � SIZE_MAX et au fait qu'on doit pouvoir repr�senter p1 - p2 aussi bien que p2 - p1. [en fait, on peut voir un prtdiff_t comme la donn�e d'un size_t et d'une direction]. Pierre
